bobcat7532010, let me clarify...I have a Toolcat 5600. It is the "D" variant (started production in 2007). My manual is for the "D" version. (The differences between the 5600 "A", "B", "C", and "D" variants can be found within this forum; however, if you have independent coil suspension on all four corners you have a "D".)
From what I was told that the oil was all the same. Dealer does not know either. Had to order the oil from dealer but would like to know what weight of oil it takes>>
